I don't know if you have ever seen these seeds in life or not... But, they are very light, and fly away with a slight breeze. I would think that is what those are for, to catch air current and fly... then when it hits something wet, they soak up water, get heavy and begin to grow there. (Where water is) that is how those terrible "dandy lions" do it in your yard.. you know the ones.. that you pick and blow the white things and they fly everywhere? hehe[b said:Quote[/b] (PlantAKiss @ May 21 2004,6:02)] I wonder if the bristles on the seeds served the purpose to stick in animal fur and get transported around...
